Virtual Reality for Pain and Anxiety Relief in Labor

This multicenter randomized controlled trial evaluates the effectiveness of a virtual reality hypnosis device (HypnoVR) in managing pain and anxiety during labor. Women in the latent and active phases of labor will be randomly assigned to either a VR intervention group or a control group receiving standard care.

Primary outcomes include pain level, measured using the Visual Analogue Scale (VAS), and anxiety level, assessed with the State-Trait Anxiety Inventory (STAI-Y). Both will be evaluated before and after the intervention.

Secondary outcomes include maternal vital signs (blood pressure and pulse), labor parameters (contraction frequency, duration, and intensity via NST), fetal parameters (heart rate and decelerations via Doppler), and maternal satisfaction (measured postpartum using a VAS satisfaction scale).

This study aims to determine whether HypnoVR can be an effective non-pharmacological method for improving the labor experience.
